After investing billions into the iPhone, Sprint is trying to play catch with Verizon and AT&T and deliver 4G LTE data across the U.S. They already have 4G LTE in nearly 200 cities, or are in the process of delivering it, but they’ll need to add a lot more coverage if they really want to compete with AT&T and Verizon.

Yesterday, Sprint announced that they are going to bring 4G LTE to 28 additional cities in the U.S. within the next few months. If you’re in one of the new cities, Sprint says that you can actually uses the 4G LTE network during the pre-launch phase as soon as you get a signal.

Here’s a list of all the new places that will get some juicy LTE later this year:

The iPad may be the king of tablets in some markets, but Apple’s device cannot compete with the Nexus 7 in Japan. Its premium price tag is causing tablet buyers to opt for Google’s 7-inch slate instead, despite its smaller display and lack of a rear-facing camera. One survey of Japanese electronics stores has found that the Nexus 7 has claimed 44.4% of the tablet market.

The popular Dolphin Browser for Android and iOS has been updated today to introduce a number of handy new features. In addition to one-tap sharing to Facebook and Twitter, users can enjoy Evernote clipping, and the ability to sync bookmarks and tabs between Dolphin and their desktop browser.

AT&T could acquire a European carrier as it looks to expand its business overseas, The Wall Street Journal reports. The company is reportedly looking at way in which it can escape the growth constraints in the United States by entering a new wireless market where it can “upgrade technology and rollout more lucrative pricing strategies.”

Although AT&T is only identifying targets at this point, it’s though the company could announce a deal before the end of the year.

The Sony Tablet S could soon have a successor.

Specifications for Sony’s upcoming Xperia Tablet Z were leaked on Wednesday, and we were looking forward to seeing the slate’s grand unveiling at Mobile World Congress in Barcelona next month. But according to one Japanese carrier, Sony’s new flagship tablet will be unveiled on the company’s home turf on January 22.
